What you should know about digital gauge accuracy… Terminal Point versus Best Fit Straight Line Accuracy. Ashcroft Type 2070 Digital Gauge with Terminal Point AccuracyBENEFIT

• All points between zero and full-scale will be within stated accuracy

• Allows zeroing of gauge at start-up to eliminate any sensor offset

Competitive Digital Gauges with Best Fit Straight Line (BFSL) Accuracy

• Linearity error mini-mized by “best” fitting a straight line to a non-linear curve

• BFSL gauges may have a zero offset at calibration that must be maintained to ensure accuracy throughout range

PROBLEM• Re-zeroing gauge may invalidate published accuracy

specification

• Zero offset at start-up may be the result of either: - BFSL Calibration - Zero Drift

BFSL minimizes linearity errorby “best” fitting a straight lineto a non-linear curve
